This document describes the features of KLM-9017-003 1 SM3418 / SM3418-(B) LED lamp, including green colored transparency lens and low power consumption.
The SM3418 (SM3418-(B)) LED lamp from AK Semiconductor features a green‑colored transparency lens, low power consumption, and a compact 3.8 mm × 3.0 mm package. The document lists mechanical dimensions, pin connections (anode and cathode), and two package styles – straight type and stopper type.
Key electrical data include absolute maximum ratings such as 85 mW power dissipation, 30 mA forward current, 4 V reverse voltage, and operating temperature range –25 °C to 85 °C. Typical performance values are given for forward voltage (2.8 V at 20 mA), luminous intensity (27 mcd), peak wavelength (570 nm), and spectrum bandwidth (30 nm). Characteristic diagrams illustrate forward current versus voltage, radiation patterns, and spectral distribution.
